Choosing an FFC/FPC adapter board is mostly a matching exercise: the cable's pin count, socket-side pitch, and needed header arrangement matter more than a small listed-price gap. These two uxcell Cable Connector boards serve different connector formats, so the best choice is the one whose stated configuration aligns with the connection you need to make.
Quick verdict
Start with the connector requirements, then use price as a secondary tie-breaker. The listed-price spread is $4.66: the 28-pin board is listed at the higher end, while the 4-pin board sits at the lower end. Neither is a general substitute for the other because their stated pin counts, pitches, and layouts differ.

Where each board wins
The 28-pin right-angle board wins for an angled header arrangement. Its title specifically calls out a double-row right-angle pin header adapter, making it the clearer match when that directional format is part of the build requirement.
The 4-pin straight-needle board wins for the named straight-needle pull-down arrangement. It is the more direct choice when a compact four-pin adapter format, rather than a larger multi-pin layout, is the goal.
FFC FPC Connector Board 28 Pins Double Row Right Angle Pin Header Adapter

This board is tailored to a 28-pin FFC/FPC connection. Its stated specification combines a 0.5 mm FPC socket-side pitch with a 1.0 mm back-side pitch and a 2.54 mm DIP pitch. Choose it when the cable and board design call for those measurements, especially when the right-angle header arrangement is part of the required layout. The 33 x 40 mm overall board size also gives this option a larger stated footprint than the four-pin alternative. Its limitation is that the configuration is highly specific: the 28-pin and 0.5 mm socket-side format needs to match the intended connection. It also carries the higher USD 19.50 listed price.
4Pin 1.0 to 2.54 mm Double Row Straight Needles Pull-down FFC FPC Adapter Board

The four-pin board is the focused pick for a connection requiring 4 pins, a 1 mm FPC socket-side pitch, a 0.5 mm back-side pitch, and a 2.54 mm DIP pitch. Its stated 26 x 17.5 mm size is smaller than the 28-pin board's dimensions, and the title identifies the double-row straight-needles pull-down format. At USD 14.84, it has the lower listed price in this comparison. The limitation is equally concrete: its four-pin, 1 mm socket-side configuration is a particular connector match, not an interchangeable stand-in for a different pin count or pitch requirement.
Final choice by use case
Choose the FFC FPC Connector Board 28 Pins Double Row Right Angle Pin Header Adapter for a build that calls for the angled header form and its stated higher-count connector format. Choose the 4Pin 1.0 to 2.54 mm Double Row Straight Needles Pull-down FFC FPC Adapter Board when the required connection centers on the straight-needle pull-down form and four-pin dimensions. In short, match the cable and board specification first; the $4.66 listed-price difference comes after fit.
